Onsite Technician - Unprofessional and unwilling to complete job despite still being on-site

I had appointment for a technician to come onsite 11/13/26 with an arrival window of “between 2:00p-4:00p” …

The technician apparently arrived right at 2:00p, and I unfortunately didn't hear him at first. When I checked outside at 2:20p, he was already walking away. Even though he was still at the property and well within the two-hour appointment window, he was visibly annoyed and said that he had already canceled the job due to waiting. Instead of simply coming inside to do the work he was already there for, he chose to leave—forcing me to go through the hassle of rescheduling all over again. Extremely frustrating and poor customer service per this technician’s conduct.
